STANDARDS

CCSS.3.MD.A.2 Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem. Excludes compound units such as cm³ and finding the geometric volume of a container. Excludes multiplicative comparison problems (problems involving notions of "times as much"; see Glossary, Table 2).

TEKS.4.8.C solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate.

TEKS.3.7.D determine when it is appropriate to use measurements of liquid volume (capacity) or weight; and

TEKS.3.7.E determine liquid volume (capacity) or weight using appropriate units and tools.

IN.3.M.2 Choose and use appropriate units and tools to estimate and measure length, weight, and temperature. Estimate and measure length to a quarter-inch, weight in pounds, and temperature in degrees Celsius and Fahrenheit.

IN.3.M.1 Estimate and measure the mass of objects in grams (g) and kilograms (kg) and the volume of objects in quarts (qt), gallons (gal), and liters (l). Add, subtract, multiply, or divide to solve one-step real-world problems involving masses or volumes that are given in the same units (e.g., by using drawings, such as a beaker with a measurement scale, to represent the problem).

VA.CE.3.3.b create and solve single-step and multistep practical problems involving sums or differences of two whole numbers, each 9,999 or less.

VA.MG.4.8.b estimate and measure weight/mass and describe the result in U.S. Customary and metric units;

VA.CE.5.4 The student will create and solve single-step and multistep practical problems involving addition, subtraction, multiplication, and division of whole numbers.
